In view from you
Nobody watches Kosmos-1603 go over, but a receiver still asks whether it is above the horizon. Say where you are and this card answers.
Your position is rounded to about a kilometre and sent only to the Orbinauts API, to find the pass.
No brightness has been published for Kosmos-1603, so it is not a naked-eye satellite and no city page carries pass times for it. Nothing here estimates one.
Seeing it
There is nothing to go outside for: it is too faint to see with the naked eye from anywhere on Earth.
Timeline

Launched, on the day GCAT records. Source
- Close approach
On Saturday, Oct 31 at 5:39 AM UTC, a fragment of Meteor 1-22 (NORAD 36302) was to pass within 69 m of Cosmos 1603 (NORAD 15333). The chance was about 1 in 8,000.

No operator publishes an ephemeris for Kosmos-1603, so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to Kosmos-1603 is reported for the next three days.
From Space-Track’s public conjunction messages; the latest report was issued Nov 9, 2026, 5:39 AM, 2 hours old. Only approaches serious enough to be reported publicly are listed: within three days and, for two bodies near the Earth, closer than a kilometre with a chance of a collision above 1 in 10,000, the level at which NASA moves the ISS.
Launched with
Kosmos-1603 shares its launch, 1984-106, with 4 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| SL-12 R/B(2) | Rocket body |
| SL-12 R/B(AUX MOTOR) | Rocket body |
| SL-12 R/B(AUX MOTOR) | Rocket body |
| COSMOS 1603 DEB | Debris |
Read from the international designators of the US catalogue: the year and the launch number every piece of one launch shares. A body that has come down is no longer listed.
